Definitions
- the invention relates to a method for electrically heating seats, in particular vehicle seats, by means of at least one flat heating element, the insulated heating conductor of which is covered on both sides.
- Integrated electrical seat heaters have been state of the art for many years , particularly in vehicle seats.
- the actual seat usually textile seat heaters are glued on a foam cushion core with or in the B ezugstoff pockets formed pushed in and in some cases also attached.
- the size and number of the heating element to be arranged on the upholstery are basically determined by the spatial shape of the seat, the individual shape sections generally forming the delimitation of the heating elements.
- fastening with tensioning wires is often a pre-programmed breaking point, which one tries to avoid by means of transitions into soft, multi-core copper wires.
- the connection points between the heating elements and the copper wire are labor-intensive and the bypassing of the tension wire, which is also practiced, is difficult. It is therefore an object of this invention to name a method of the type described in the introduction, which absorbs the deformations through use, without the elastic behavior of the foam cushion core being restricted.
- the solution to this problem according to the invention provides that at least one meandering insulated heating conductor is laid on each load-bearing film made of thermoplastic and is usually covered by the same film, the thermal dimensional stability of the heating conductor insulation exceeding that of the films by approximately 50%, that a firmly connected heating element is then formed by the supply of heat and pressure, the heating conductor of which lies in the meandering channels formed in accordance with the laying without the formation of a bond with the foils, and that the elastic properties of the heating element in connection with the choice of the smallest possible meandering distance can be set so that in the de-energized state there is a large length of the heating conductor, so that the heating element can be stretched at least twice the length and width without damage at each stressed point.
- the meandering laying of insulated heating conductors on a supporting film made of elastic plastic can be realized in a simple manner with an ironing press, as is shown by DE - PS 30 13 778.
- the criterion of this device is that the actual press plate is connected to an ironing plate made of elastic, porous, ironing temperature-resistant material with high thermal conductivity by adhesive and that the material constants of the ironing plate which show the elasticity behavior are selected so that the volume of the needles of the needle template is full during the pressing process is displaceable in it. the displaced volume is recoverable after lifting off the press plate connected to it.
- the heating conductor is laid using pins arranged according to the laying plan, each of which determines the deflection of the heating conductor in a different direction. Changing the installation plan is very easy.
- the thermal dimensional stability of the heating conductor insulation must exceed that of the film.
- the subsequent connection of the heating elements between the foils takes place by supplying heat and pressure, as is made possible, for example, by the aforementioned training according to DE-PS 30 13 778.
- What is essential for the quality of the heating element is the length of the heating conductor in a stress-free state in connection with the elastic properties of the heating element.
- the large number of proposed meandering loops that run close to one another allow the design of a heating conductor length that is above average in its length dimensioning, so that when the duct created by the insulation is deformed by stress, the heating conductor is not damaged in any way at the given stretching of the meanders, or vice versa the heating conductor is overused.
- the airtight cover material of the seat or the backrest is drawn by vacuum onto a shape formed with an embossed surface, the surfaces of the heating elements facing this being glued or bonded to the inside of the cover. are laminated, and that when the shape is foamed, the heating elements that are directed towards the underside of the cover are firmly connected to the cover.
- foils are processed in thicknesses of 20 to 200 n, and that the heating conductor is formed from an at least 7-wire stranded wire with single wires less than 0.1 mm in diameter, with a thin, on the two Non-binding foils can be provided.
- the large-area heating elements provided for heating vehicle seats each consist of two thermoplastic films of the same size and the same properties, with a co-polyamide base being assumed.
- the thickness of the film is 0.08 mm, the tensile strength approx. 8 kp / mm 2 , the modulus of elasticity approx. 250 kp / mm 2 and the temperature resistance according to Martens approx. 100 ° C.
- the insulation of the heating conductor also consists of a co-polyamide or the like material and has a tensile strength of 6 kp / mm 2 , an elastic modulus of 190 kp / mm 2 and a temperature resistance according to Martens of 230 ° C.
- thermoplastic plastic films The insulated heating conductor laid between the thermoplastic plastic films is, as already described, connected by an ironing press or the like while maintaining its lubricity between the films.
- the higher dimensional stability of the insulation ensures the mobility of the heating conductor between the foils.
- the individual heating elements can only be fixed under the cover of the seat and under the cover of the backrests or integrated on the foam cushion parts.

Die so hergestellten Heizelemente werden den Polsterkernen verbunden, wobei im Falle des Tiefziehens die Anordnung an der Innenseite des Bezuges liegt.The invention relates to a method for the electrical heating of vehicle seats by at least one flat heating element, the insulated heating conductor of which is covered on both sides. It is the object of this invention to provide a method of this kind which absorbs the deformations in use without restricting the elastic behavior of the foam cushion core. According to the invention it is provided that at least one meandering insulated heating conductor is laid on each load-bearing film made of thermoplastic material and is covered by a generally the same film, the thermal dimensional stability of the heating conductor insulation exceeding that of the films by approximately 50%, that is subsequently by supply a firmly connected heating element is formed by heat and pressure, the heating conductor of which lies in the meandering channels formed in accordance with the laying without any binding with the foils, and that the elastic properties of the heating element are set in connection with the choice of the smallest possible meandering distance, that in the de-energized state there is a large length of the heating conductor, so that the heating element can be stretched at least twice the length and width without damage at each stressed point.

Description
Die Erfindung betrifft ein Verfahren zum elektrischen Beheizen von Sitzen, insbesondere Fahrzeugsitzen, durch mindestens ein flächig ausgebildetes Heizelement, dessen isolierter Heizleiter beidseitig abgedeckt ist.The invention relates to a method for electrically heating seats, in particular vehicle seats, by means of at least one flat heating element, the insulated heating conductor of which is covered on both sides.
Integrierte elektrische Sitzbeheizungen sind be- sonders in Fahrzeugsitzen seit vielen Jahren Stand der Technik.Integrated electrical seat heaters have been state of the art for many years , particularly in vehicle seats.
Je nach Sitzausführung werden die eigentlichen, meist textilen Sitzbeheizungen auf einem Schaumstoffpolsterkern mit aufgeklebt oder auch in vom Bezugstoff gebildete Taschen eingeschoben und fallweise auch angeheftet. Die Größe und die Anzahl der auf dem Polster anzuordnenden Heizelement werden im Grunde genommen durch die Raumform des Sitzes bestimmt, wobei die einzelnen Formabschnitte in der Regel die Abgrenzung der Heizelemente bilden.Depending on the embodiment, the actual seat, usually textile seat heaters are glued on a foam cushion core with or in the B ezugstoff pockets formed pushed in and in some cases also attached. The size and number of the heating element to be arranged on the upholstery are basically determined by the spatial shape of the seat, the individual shape sections generally forming the delimitation of the heating elements.
Alle diese Ausführungen beinhalten die Gefahr, daß durch eine nicht gegebene, vollkommen sichere Be- festigung der textilen Heizelemente eine Faltenbildung innerhalb des Heizelementes möglich wird, die zum Bruch des Heizleiters führen kann.All of these versions include the risk that by not given completely safe loading - fixing the textile heating elements wrinkling within the heating element is possible, which can lead to breakage of the heat conductor.
Außerdem stellt die Befestigung mittels Spanndrähten oft eine vorprogrammierte Bruchstelle dar, welche man durch Übergänge in weiche, vieladrige Kupferlitzenzu vermeiden versucht. Die Verbindungsstellen zwischen Heizelementen und der Kupferlitze sind arbeitsaufwendig und die ebenfalls praktizierte seitliche Umgehung des Spanndrahtes schwierig. Es ist deshalb Aufgabe dieser Erfindung, ein Verfahren nach der eingangs beschriebenen Art zu nennen, das die Verformungen durch den Gebrauch aufnimmt, ohne daß das elastische Verhalten des Schaumpolsterkernes eingeengt wird.In addition, fastening with tensioning wires is often a pre-programmed breaking point, which one tries to avoid by means of transitions into soft, multi-core copper wires. The connection points between the heating elements and the copper wire are labor-intensive and the bypassing of the tension wire, which is also practiced, is difficult. It is therefore an object of this invention to name a method of the type described in the introduction, which absorbs the deformations through use, without the elastic behavior of the foam cushion core being restricted.
Die erfindungsgemäße Lösung dieser Aufgabe sieht vor, daß auf jeweils einer tragenden Folie aus thermoplastischem Kunststoff zumindest ein mäanderförmig isolierter Heizleiter verlegt und durch eine in der Regel gleiche Folie abgedeckt wird, wobei die thermische Formbeständigkeit der Heizleiterisolation die der Folien um ca. 50% überschreitet, daß anschließend durch Zufuhr von Wärme und Druck ein fest verbundenes Heizelement gebildet wird, dessen Heizleiter ohne Entstehen einer Bindung mit den Folien in den entsprechend der Verlegung ausgebildeten mäanderförmigen Kanälen einliegt, und daß die elastischen Eigenschaften des Heizelementes in Verbindung mit der Wahl eines möglichst geringen Mäanderabstandes so eingestellt werden, daß in spannungsfreiem Zustand eine große Länge des Heizleiters gegeben ist, so daß das Heizelement an jeder belasteten Stelle mindestens bis zur doppelten Länge und Breite zerstörungsfrei dehnbar ist.The solution to this problem according to the invention provides that at least one meandering insulated heating conductor is laid on each load-bearing film made of thermoplastic and is usually covered by the same film, the thermal dimensional stability of the heating conductor insulation exceeding that of the films by approximately 50%, that a firmly connected heating element is then formed by the supply of heat and pressure, the heating conductor of which lies in the meandering channels formed in accordance with the laying without the formation of a bond with the foils, and that the elastic properties of the heating element in connection with the choice of the smallest possible meandering distance can be set so that in the de-energized state there is a large length of the heating conductor, so that the heating element can be stretched at least twice the length and width without damage at each stressed point.
Die mäanderförmige Verlegung isolierter Heizleiter auf einer tragenden Folie aus elastischem Kunststoff läßt sich auf einfache Weise mit einer Bügelpresse, wie sie durch die DE-PS 30 13 778 ausgewiesen ist, realisieren.The meandering laying of insulated heating conductors on a supporting film made of elastic plastic can be realized in a simple manner with an ironing press, as is shown by DE - PS 30 13 778.
Das Kriterium dieser Vorrichtung ist, daß die eigentliche Preßplatte mit einer Bügelplatte aus elastischem, porösen, bügeltemperaturbeständigen Material hoher Wärmeleitfähigkeit durch Kleber verbunden ist und daß die das Elastizitätsverhalten ausweisende Materialkonstanten der Bügelplatte so gewählt sind, daß das Volumen der Nadeln der Nadelschablone während des Preßvorganges voll in ihr verdrängbar ist.bzw. das verdrängte Volumen nach Abheben der mit ihr verbundenen Preßplatte rückbildbar ist.The criterion of this device is that the actual press plate is connected to an ironing plate made of elastic, porous, ironing temperature-resistant material with high thermal conductivity by adhesive and that the material constants of the ironing plate which show the elasticity behavior are selected so that the volume of the needles of the needle template is full during the pressing process is displaceable in it. the displaced volume is recoverable after lifting off the press plate connected to it.
Die Verlegung des Heizleiters erfolgt um nach dem Verlegeplan eingeordnete Stifte, die jeweils die Umlenkung des Heizleiters in eine andere Richtung bestimmen. Die Änderung des Verlegeplans ist denkbar einfach.The heating conductor is laid using pins arranged according to the laying plan, each of which determines the deflection of the heating conductor in a different direction. Changing the installation plan is very easy.
Um die Gleitfähigkeit des isolierten Heizleiters aufrechtzuerhalten, muß die thermische Formbeständigkeit der Heizleiterisolierung die der Folie überschreiten. Die anschließend stattfindende Verbindung der Heizelemente zwischen den Folien erfolgt durch Zufuhr von Wärme und Druck, wie sie beispielsweise durch die bereits erwähnte Ausbildung nach der DE-PS 30 13 778 ermöglicht wird.In order to maintain the sliding ability of the insulated heating conductor, the thermal dimensional stability of the heating conductor insulation must exceed that of the film. The subsequent connection of the heating elements between the foils takes place by supplying heat and pressure, as is made possible, for example, by the aforementioned training according to DE-PS 30 13 778.
Wesentlich für die Qualität des Heizelementes ist die in spannungsfreiem Zustand gegebene Länge des Heizleiters in Verbindung mit den elastischen Eigenschaften des Heizelementes.What is essential for the quality of the heating element is the length of the heating conductor in a stress-free state in connection with the elastic properties of the heating element.
Die Vielzahl der vorgeschlagenen, in engem Abstand zueinander verlaufenden Mäanderschlingen erlauben die Auslegung eines in seiner Längendimensionierung überdurchschnittliche Heizleiterlänge, so daß bei Verformung durch Belastung der durch die Isolierung entstandene Kanal in keiner Weise den Heizleiter bei der gegebenen Streckung der Mäander zueinander geschädigt oder umgekehrt der Heizleiter überbeansprucht wird.The large number of proposed meandering loops that run close to one another allow the design of a heating conductor length that is above average in its length dimensioning, so that when the duct created by the insulation is deformed by stress, the heating conductor is not damaged in any way at the given stretching of the meanders, or vice versa the heating conductor is overused.
In diesem Zusammenhang wird vorgeschlagen, die Heizleiter in Abstand kleiner als 15 mm mäanderförmig einzubetten.In this context, it is proposed to embed the heating conductors in a meandering manner at a distance of less than 15 mm.
Zur Herstellung bei Verwendung von Sitz oder Lehne bildenden Polster-Formteilen wird vorgeschlagen, daß diese mit einem Bezugstoff bespannt werden, wobei die unter dem Bezug liegenden Oberflächen des Schaumteiles zuvor auf die unter dem Bezug liegenden Oberflächen des Schaumteiles anzuordnenden Heizelemente angeschäumt oder angeklebt werden.For the production when using seat or backrest-forming upholstery moldings, it is proposed that these be covered with a cover material, the underlying surfaces of the foam part being previously foamed or glued to the heating elements to be arranged below the surfaces of the foam part.
Hierbei sollte dem Anschäumen ein Vorrang vor dem Ankleben gegeben werden, wobei allerdings - je nach Zugänglichkeit - oft unterschiedliche Befestigungen vorgesehen werden müssen.It should the A nschäumen be given a priority over the sticking, although - depending on availability - often different attachments must be provided.
Zur Herstellung von Sitz- oder Lehnenpolsterungen im Tiefziehverfahren wird vorgeschlagen, daß der luftdichte Bezugstoff des Sitzes bzw. der Lehne durch Vakuum auf eine mit geprägter Oberfläche ausgebildete Form gezogen wird, wobei auf der Innenseite des Bezuges die zu diesem gerichtete Oberflächen der Heizelemente angeklebt bzw. ankaschiert sind, und daß bei Zuschäumen der Form die mit den zu der Unterseite des Bezuges gerichteten Heizelemente sich fest am Bezug verbinden.For the manufacture of seat or backrest upholstery in the deep-drawing process, it is proposed that the airtight cover material of the seat or the backrest is drawn by vacuum onto a shape formed with an embossed surface, the surfaces of the heating elements facing this being glued or bonded to the inside of the cover. are laminated, and that when the shape is foamed, the heating elements that are directed towards the underside of the cover are firmly connected to the cover.
Zum Aufbau wird vorgeschlagen, daß Folien in Stärken von 20 bis 200 n verarbeitet werden, und daß der Heizleiter aus einer mindestens 7-adrigen Litze mit Ein- .zeldrähten unter 0,1 mm Durchmesser gebildet wird, die mit einer dünnen, an den beiden Folien nicht bindenden Isolierung versehen werden.To build it up, it is proposed that foils are processed in thicknesses of 20 to 200 n, and that the heating conductor is formed from an at least 7-wire stranded wire with single wires less than 0.1 mm in diameter, with a thin, on the two Non-binding foils can be provided.
Das vorgeschlagene Verfahren wird in vollem Umfang der Aufgabenstellung gerecht.The proposed procedure fully meets the task.
Die zur Beheizung von Fahrzeugsitzen vorgesehenen, großflächig ausgebildeten Heizelemente bestehen jeweils aus zwei thermoplastischen Folien gleicher Größe und gleicher Eigenschaften, wobei von einer Co-Polyamidbasis ausgegangen wird. Die Dicke der Folie beträgt 0,08 mm, die Zugfestigkeit ca. 8 kp/mm2, der Elastizitätsmodul ca 250 kp/mm2 und die Temperaturformbeständigkeit nach Martens etwa 100° C.The large-area heating elements provided for heating vehicle seats each consist of two thermoplastic films of the same size and the same properties, with a co-polyamide base being assumed. The thickness of the film is 0.08 mm, the tensile strength approx. 8 kp / mm 2 , the modulus of elasticity approx. 250 kp / mm 2 and the temperature resistance according to Martens approx. 100 ° C.
Die Isolierung des Heizleiters besteht ebenfalls aus einem Co-Polyamid oder dgl. Werkstoff und weist eine Zugfestigkeit von 6 kp/mm2, einen Elastizitätsmodul von 190 kp/mm2 und eine Temperaturformbeständigkeit nach Martens von 230°C aus.The insulation of the heating conductor also consists of a co-polyamide or the like material and has a tensile strength of 6 kp / mm 2 , an elastic modulus of 190 kp / mm 2 and a temperature resistance according to Martens of 230 ° C.
Der zwischen den thermoplastischen Kunststoff-Folien verlegte isolierte Heizleiter wird, wie bereits beschrieben, bei Aufrechterhaltung seiner Gleitfähigkeit zwischen den Folien, durch eine Bügelpresse oder dgl. verbunden. Die höhere Formbeständigkeit der Isolierung sichert die Beweglichkeit des Heizleiters zwischen den Folien.The insulated heating conductor laid between the thermoplastic plastic films is, as already described, connected by an ironing press or the like while maintaining its lubricity between the films. The higher dimensional stability of the insulation ensures the mobility of the heating conductor between the foils.
Die einzelnen Heizelemente können sowohl lediglich unter den Bezug der Sitzfläche als auch unter den Bezug der Lehnen fixiert werden bwz.auf den Schaumpolsterteilen integriert werden.The individual heating elements can only be fixed under the cover of the seat and under the cover of the backrests or integrated on the foam cushion parts.
